The ribs surrounding the mating latch prevent wires from becoming caught underneath the latch. The polarization feature prevents mating housings of different sizes and keying configuration. The housings have a mating keying feature available in 4 configurations (A, B, C, and D) to prevent mis-mating. The housings are also color coded for 4 available housing materials: standard, high temperature, glow wire, and hot wire. In addition, the panel mount cap housing features panel stops and flexible panel latches. In use, the panel latches secure the housing to a panel without the use of mounting hardware. Optional connector position assurance (CPA) device and terminal position assurance (TPA) device (also called locking plate) are available to install onto the housing. These devices provide added security to ensure that the mated housings remain together and ensure proper contact insertion and retention in the circuit cavities. The CPA device prevents the plug housing mating latch from being accidentally depressed. Each contact features a wire barrel, insulation barrel, contact stabilizer, and center key (plug) or side keys (tab). The underside at the mating end of the contact has a latch opening that engages the housing contact cavity latch and secures the contact to the housing. The key(s) only allow the contact to be inserted into the associated housing. 2. REFERENCE MATERIAL 2.1.

Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the product material. B. Shelf Life Contacts are shipped on continuous reels and housings are supplied in plastic bags in cartons. The product should remain in the shipping containers until ready for use to prevent deformation to components. The product should be used on a first in, first out basis to avoid storage contamination that could adversely affect performance. Rev F 3 of 14 114-106118 C. Reels When using reeled contacts, store coil wound reels horizontally. When storing partial reeled contacts, the end of the strip should be secured to the flange using a wire tie or similar method. D. Chemical Exposure Product must not be stored near any chemical listed below as they may cause stress corrosion cracking in the material. Alkalies Amines Ammonia Carbonates Citrates Nitrites Phosphates Citrates Sulfur Nitrites Sulfur Compounds Tartrates NOTE Contacts that contain brass must not be stored or used in environments where these chemicals exist. 3.2. Wire Selection and Preparation The contacts accept 1 stranded copper wire sizes 0.34 to 3.30 mm2 [22 to 12 AWG] or 2 stranded copper wires sizes 0.34 to 0.89 mm2 [22 to 18 AWG] with an insulation diameter range of 2.00 to 4.25. Each wire must be stripped to the dimension given in Figure 2. CAUTION Care must be taken not to nick, scrape, or cut any part of the wire during the stripping operation. Note: Not to Scale 4.5±0.3 Strip Length Figure 2 3.3. Contact Crimp A. Cutoff Tab and Burr The cutoff tab is the remaining portion of the carrier strip after the contact is cut from the strip, and the burr is the result from the cutoff tab shearing. The cutoff tab and burr must not exceed the dimension given in Figure 3. B. Wire Barrel Crimp The crimp applied to the wire barrel portion of the contact is the most compressed area and is most critical in ensuring optimum electrical and mechanical performance of the crimped contact. The crimp must be centered on the closed wire barrel. The crimp must result in an “F” crimp where the wire barrel forms a closed seam with no evidence of loose wire strands or wire strands visible in the seam. The crimp height and width must be within the dimensions provided in Figure 3. C. Insulation Barrel Crimp The crimp applied to the insulation barrel of the contact must result in either an “F” crimp where the insulation barrel forms a closed seam with no evidence of wire insulation in the seam or an overlap crimp where the tips of the insulation barrel wraps overlap each other and wrap firmly around the wire insulation without cutting into the wire insulation. The crimp height and width must be within the dimensions provided in Figure 3. Rev F 4 of 14 114-106118 D. Contact Stabilizer The contact stabilizer must not be crimped or deformed in any way. The width of the stabilizer must be within the dimension given in Figure 3. Otherwise, in addition to reducing the function of the stabilizer, a deformed stabilizer will cause the TPA to be ineffective. E. Wire Barrel Flash Wire barrel flash is the formation that may appear on both sides of the wire barrel as the result of the crimping process. It must not exceed the dimension provided in Figure 3. F. Twist and Roll There should be no twist or roll of the wire barrel or mating portion of the crimped contact that would cause overstress or impair usage. See Figure 3. G. Wire End Extrusion The wire conductor ends must extend beyond the end of the wire barrel within the dimensions given in Figure 3. H. Bellmouths The front bellmouth and rear bellmouth shall be evident and conform to the dimensions given in Figure 3.

Contact Keying The key(s) of the contact must match the contact keying feature of the circuit cavity to allow insertion into the associated housing. B. Housing Mating Keying Feature Only plug housings and cap housings with identical keying configuration will mate; for example, key A will only mate with key A, etc. The TE Connectivity customer drawing provides keying configurations. Rev F 8 of 14 114-106118 3.5. Contact Insertion and Extraction A. Insertion Each contact must be aligned with the appropriate circuit cavity from the wire end of the housing so that the contact key(s) faces the housing mating latch (plug housing) or latch retainer (cap housing) for the first and third rows, and for the second row, the contacts must be inverted. The orientation of the contacts must alternate from row to row. Refer to Figure 6. The contact must be inserted into the circuit cavity until the contact internal latch locks onto the circuit cavity locking finger. See Figure 7. NOTE Gently pulling on the wire after the contact has been inserted will ensure that the contact is locked. Note: For clarity, the optional TPA device and contacts are shown outside of the housing.

Extraction If the optional TPA device is used, the contacts cannot be removed until the TPA is removed from the housing. Contacts must be removed individually from the housing using the extraction tool given in Paragraph 5.4 and the instructions for removing a contact given in 408-32206. After extraction, the contact must be inspected for damage or deformation; if evident, the contact must be replaced. NOTE If the contact has been pushed or pulled out of the housing, the rework procedure given in 408-32206 must be followed. 3.6. Optional TPA and CPA Devices An optional TPA device is available for the plug housing and cap housing, and an optional CPA device is available for the cap housing. The following requirements apply for installation (refer to Figure 6): NOTE All contacts must be inserted before the devices can be installed into the housing. — The CPA device must be fully inserted into the opening at the top of the wire end of the plug housing until the latch engages the plug housing. There should be an audible click. After installation, the tips of the legs must be visible at the top of the mating face of the plug housing. — The TPA device must be installed onto the wire end of the housing so that the latches are secure to the housing TPA locking tabs. There should be an audible click. If the latches do not reach the locking tabs, this indicates that one or more contacts has not been fully inserted or the contact internal latch has not locked onto the circuit cavity. The following requirements apply for removal (refer to Figure 6): — The CPA device must be removed by depressing the tips of the legs, and sliding the CPA device out of the housing. — The TPA device must be removed by lifting each latch so that it clears the housing TPA locking tab, and pulling the TPA device straight from the housing. 3.7. Continuity Testing For continuity testing of the housing, design guidelines for the test fixture and pogo pin (probe) must be considered (refer to Paragraphs 2.3 and 2.4); otherwise damage to the contacts may occur. All contacts must be inserted and locked into the housing prior to placing the housing into the test fixture. To avoid deformation to the contact, it is extremely important to ensure specific probe location. See Figure 8.

Panel Mounting Recommended panel cutout dimensions are provided on the customer drawing for the specific cap housing. The cap housing must be inserted through the panel in the same direction that the cutout was punched until the panel stops sit against the panel so that the flexible panel latches engage the panel. No hardware is required. See Figure 9. To remove the cap housing from the panel, both latches must be simultaneously depressed, then the cap housing must be gently pulled straight out of the panel. If there is no damage to the cap housing, the cap housing can be re-mounted. Direction of Punch of Cutout Panel Cutout Wire (Ref) Panel Latch (2 Places) Engaged to Panel Panel Stop (4 Places) Against Panel Cap Housing Figure 9 3.9. Mating and Unmating The mating face of the cap housing must align with the mating face of the plug housing, then the housing must be pushed together until the mating latch is secured to the latch retainer. There should be an audible click. Refer to Figure 6. To unmate the housings, if used, the CPA device must be withdrawn (but not removed). The plug housing mating latch must be depressed until it is released from the latch retainer, then the housings can be pulled straight apart. CAUTION These housings are not intended to be used as an electrical interruption device. To avoid degradation to the contacts, there must be no current flow when unmating. 3.10. Strain Relief and Wire Dress Wires can be bundled together and supported using cable ties or electrical tape. The wires must remain perpendicular to the housing and avoid an excessively sharp bend radius. The wire bundle must be at least 76 [3.0] from the back of the housing before bending in any direction. Do not bend unsupported wires as this may cause strain on the contacts. 3.11. Replacement and Repair Damaged or defective product must not be used. The housings, contacts, CPA device, and TPA device are not repairable. A contact can be removed using the extraction tool given in Paragraph 5.4. The contact can be re-inserted into the housing provided there has been no deformation or damage to the contact latch opening or housing internal latch. Refer to Paragraph 3.5.B for contact extraction and insertion information. If the contact has been pushed or pulled out of the housing, the rework procedure given in 408-32206 must be followed. 4.
